Building a new wall. Attachment to existing drywall?

[Marcus Ericsson]

Hello all experts!

I'm working on a project to put up a wall in our living room to create a new room. The existing walls are drywall on wooden studs, and the new wall will be OSB and drywall on both sides. What I'm wondering is if/how to best attach the first and last wall studs to the existing walls? I guess there's an overriding risk of cracking in the corners if it's not done, but how do I do this best when there are no studs behind the drywall exactly where the new wall is supposed to stand? Do I need to take down a piece of the drywall to get a stud behind it, or is there an easier, but good solution? Glue/anchors? Grateful for any tips.

Do I need to remove a section of the drywall to get a stud behind it, or is there an easier but good solution? Glue/plugs? Grateful for any tips.

You attach the stud to the wall. Use construction adhesive if that's the case. Personally, I use metal stud which requires short one-layer wood screws just fine. With a wooden stud, you drill an 8mm hole in the stud and use 6x70 or 80 screws into the drywall. Screw gently and it will work out.

at the top and bottom there should be a stud in the old wall to screw into + a bit of construction adhesive on the back of the stud

Plaster anchor, maybe?
